Scorch height and volume modeling in prescribed fires: effects of canopy gaps in Pinus pinaster stands in Southern Europe
(Elsevier, 2022)The use of prescribed fire has been on the rise in recent years owing to its effectiveness in surface fuel reduction, its implementation cost, and the possibility of firefighter training. However, greater knowledge regarding ... -
Semi-automated stand delineation in Mediterranean Pinus sylvestris plantations through segmentation of LiDAR data: the influence of pulse density
(Science Direct, 2017)Traditionally, forest-stand delineation has been assessed based on orthophotography. The application of LiDAR has improved forest management by providing high-spatial-resolution data on the vertical structure of the forest. ... -
Site index estimation using airborne laser scanner data in Eucalyptus dunnii maide stands in Uruguay
(MDPI, 2023)Intensive silviculture demands new inventory tools for better forest management and planning. Airborne laser scanning (ALS) was shown to be one of the best alternatives for high-precision inventories applied to productive ... -
Small-Scale Abiotic Factors Influencing the Spatial Distribution of Phytophthora cinnamomi under Declining Quercus ilex Trees
(MDPI, 2020)Phytophthora root rot is considered one of the main factors associated with holm oak (Quercus ilex L.) mortality. The effectiveness and accuracy of soilborne pathogen and management could be influenced by soil spatial ... -
Soil Management, Irrigation, and Fertilisation Strategies for N2O Emissions Mitigation in Mediterranean Agricultural Systems
(MDPI, 2022)Feeding a growing population, which will reach 10 billion in 2050, is a major challenge. Another major challenge is to increase crops’ productivity in a sustainable way, as the increase in agricultural inputs may lead to ... -
Soil-Organic-Carbon Concentration and Storage under Different Land Uses in the Carrizal-Chone Valley in Ecuador
(MDPI, 2019)Soil organic carbon (SOC) is an important indicator of soil quality; an elevated percentage of SOC indicates very high-quality soil, physically as well as chemically. As such, the principal objective of the present study ... -
Spatio-temporal analysis of oak decline process in open woodlands: A case study in SW Spain
(Elsevier, 2019)This study aims to characterize at landscape level the spatio-temporal dynamics of a massive oak decline that is occurring in dehesas ecosystems. We are looking at possibilities of matching with Phytophthora disease ... -
Stand Characterization of Eucalyptus spp. Plantations in Uruguay Using Airborne Lidar Scanner Technology
(MDPI, 2020)Airborne lidar scanner (ALS) technology is used in a variety of applications, including forestry. ALS has enormous potential for the estimation of relevant biometric parameters in forest plantations. This study investigates ... -
Stand Delineation of Pinus sylvestris L. Plantations Suffering Decline Processes Based on Biophysical Tree Crown Variables: A Necessary Tool for Adaptive Silviculture
(MDPI, 2021)Many planted Pinus forests are severely affected by defoliation and mortality processes caused by pests and droughts. The mapping of forest tree crown variables (e.g., leaf area index and pigments) is particularly useful ... -
Study of potential of reforested areas in the province of Manabí (Ecuador)
(Universidad de Córdoba, UCOPress, 2023)El Ecuador posee extensas áreas de bosque primario, especialmente ubicadas en la Región Amazónica, en las cordilleras de la región andina y en las zonas húmedas y secas de la región Costa. Siendo estos los principales ... -
Temporal changes in mediterranean pine forest biomass using synergy models of ALOS PALSAR-Sentinel 1-Landsat 8 Sensors
(MDPI, 2023)Currently, climate change requires the quantification of carbon stored in forest biomass. Synthetic aperture radar (SAR) data offers a significant advantage over other remote detection measurement methods in providing ... -
The ignition index based on flammability of vegetation improves planning in the wildland-urban interface: A case study in Southern Spain
(Elsevier, 2017)Forest fires in the wildland urban interface (WUI) are a widespread and growing problem due to changes in land use and climate. The impacts of WUI fire depend on the exposure of homes to dense vegetation (both natural and ... -
The influence of the soil management systems on aboveground and seed bank weed communities in olive orchards
(Wiley, 2020)The biodiversity of farmed landscapes is, in the context of agricultural intensification, a key aspect with regard to improving the sustainability of agroecosystems. Olive groves are undergoing rapid changes because of the ... -
The influence of tree and soil management on soil organic carbon stock and pools in dehesa systems
(Elsevier, 2020)This study evaluated the effect on SOC concentration, stock and fractions in a dehesa divided into two areas with different soil management. The first area was a pastured dehesa (P) with young Holm oaks, planted in 1995 ... -
The role of flagship species in the economic valuation of wildfire impacts: An application to two Mediterranean protected areas
(Elsevier, 2019)Disturbance events play an important role in ecosystem services management and species biodiversity. In this sense, species biodiversity may constitute a large proportion of the total ecosystem value, mainly in natural ... -
Thermolidar
(Oficina de Transferencia de Resultados de la Investigación, 2013)La selvicultura de precisión aprovecha nuevas herramientas tecnológicas, como son diferentes tipos de sensores (multi e híper espectrales, térmicos, LiDAR) sobre distintas plataformas (satélites, aeronaves o vehículos no ... -
Thinning Effect of C Sequestration along an Elevation Gradient of Mediterranean Pinus spp. Plantations
(MDPI, 2021)Forests are key elements in mitigating the effects of climate change due to the fact of their carbon sequestration capacity. Forest management can be oriented to optimise the carbon sequestration capacity of forest stands, ... -
Tracking the seasonal dynamics of boreal forest photosynthesis using EO-1 hyperion reflectance: sensitivity to structural and illumination effects
(IEEE, 2016)During the growing season, the photosynthesis and growth of boreal forests are regulated by physiological responses to environmental factors. Physiological variations affect the spectral properties of leaves. Linking ... -
